monoclinic zirconia crystal shape into square type crystal zirconia, with 7% of the volume change at the same time;Under 2300 ℃,
the quartet zirconia crystal shape into a stable type cubic zirconia.For preparing stabilized zirconia, usually to join CaO and MgO style or
Y2O3 as stabilizing agent, such as by heating with 1100 ~ 1200 ℃, to the preparation of stable type cubic zirconia solid solution.
The starting materials for the raw materials used in the manufacture of zirconia brick for baddeleyite and zircon.Baddeleyite is a kind of
exist in the form of oxide minerals containing zirconium, ZrO2 content 80% ~ 80%;Zircon exists in the form of the silicate minerals containing
zirconium, Zr02 theory content is 67.2%.In baddeleyite preparation of zirconia and zircon as raw materials with chemical method and fused method.
Chemical method containing zirconium chemically from the ore into the method of ZrO2.Will join the hot caustic soda zircon ore concentrate,
the reaction products zirconium sodium with concentrated hydrochloric acid washing, oxygen zirconium chloride can be obtained from (ZrOCl2, 8 h2o).
Dissolve oxygen zirconium chloride in water, adding ammonium hydroxide zirconium hydroxide precipitation generated.Zirconium hydroxide by calcination, zirconium oxide can be obtained from.The chemical reaction is as follows:
- Q: What are the ingredients in the binder of the yttrium zirconium brick?
- In the case of adhesive, the normal binder includes the solvent, curing agent, toughening agent, preservative, colorant, defoaming agent and so on.
- Q: What metal materials withstand 1000 degrees high temperature long burning contact with open flame?
- Zirconia brick can withstand 2600 degrees high temperature and good heat insulation performance and long service life
- Q: What's the difference between zirconium and zirconia? What are the fields in which applications?
- Fused zirconia is mainly used for refractory materials, such as zirconia bricks, and used in crystal materials, such as making diamond, and making high-temperature resistant coatings, etc. ~!
- Q: Continuous basalt fiberThere are several questions that we write on paper!Please let me know if you have any information about itHow to choose the heating system for the crucible furnace?The commissioning process of the furnace?
- Generation of platinum crucible and its only bushing connected electrode made of platinum rhodium alloy, and the crucible body and its relevant subsidiary components from refractories and. Liquid glass crucible by molten glass itself as an electrically heating resistor, or by a platinum alloy heater placed in the crucible for heating glass, can also use the resistance heater (with silicon carbide) by radiation heating glass in the glass, the glass liquid reaches the required temperature.
- Q: What is a zirconium drill? Is it valuable?
- In choosing zircon, you should first consider the choice of zircon, the most popular blue, blue is often considered as a panacea universal color. For women, the most important point is to coordinate with their eyes and hair, although many ladies love match, aquamarine aquamarine, but not so bright is not like zircon, zircon shine. Colorless zircon is recommended, especially want to buy a piece of jewelry, and are unwilling to invest in expensive diamond, then choose colorless zircon can be said to be saving money, shoot two hawks with one arrow, and achieves the purpose of beautifying life. Generally, a zircon ring is only a few dozen yuan.
